making a page model real-world elasticity is not IP. double-tap-to-zoom isn't either - any more than pointing or pinching or single-tapping is. these are all gestures taken from The Real World. you know, the thing we all live in, the thing that makes such interactions non-novel?
Apple should be praised for its success, but not given fealty. in fact, it should be punished for resorting to litigation rather than innovation.

Break down the price on a new Iphone or Ipad deduct the manufactured cost of the device then calculate which features are more important to the users and assign reasonable cost benefit analysis, the 3 features in question become trivial relative to the price of the device but those are the figures that should be used to determine the value added to the Samsung devices by Apple patented "gizmos". Apple does not believe than competition drives the marketplace and would rather eliminate all competition giving everyone a generic box with no need to innovate since they would be the only game in town. Apple may feel it is necessary to milk their customers for every dime possible but they should not feel that since they do it the entire industry fall in line and do the same. Shame on you Apple! Being the owner of several Apple devices and an ardent consumer of high end electronics I am appalled that Apple seeks to defeat their competition through obliteration rather than innovation. As a parent I now feel responsible to provide alternatives to Apple for all of my children as an example of capitalism gone bad. Apple will need to go a long way to convince me that they see the error of their ways, until them they should see this post as only the first of many. I am setting my watchlists to Apple, please feel free to look for my future posts.

Samsung should use diagonal swipe to increase image size with a fade out button to Auto-zoom, a ping or vibrate at the end of the page would be every bit as effective and "playful" users could even assign their own sounds such as a Homer Simpson "Dohhh" or the sound of Pacman dying just for a couple of examples. This survey was conducted by Apple and is biased for Apple it is ridiculous to assume that users would pay an average of $33.00 for each feature on a device. After paying for the electronics and activation my Droid Charge would cost over $2,000 just in features. My phone cost me less than apple believes their 3 "cute" features are worth, as a consumer I have just developed a new loathing for Apple.
